We have developed a high image quality OLED Display with motion blur reduction technology. Our latest work includes driving method which reduces motion blur using an adaptive black data insertion, brightness compensation technology, the simple structure pixel with low capacitance coupling for horizontal noise, and the multi‐function integrated gate driver. The MPRT value of the OLED display panel with a fast response time was significantly affected by the frame frequency and the compensation driving method. The decrease in the MPRT value originated from the turning of the emitting pixels off in advance resulting from providing black data. The integrated gate drivers were designed to achieve the normal display, the black data insertion, and the compensation mode. The MPRT value of the 65‐inch UHD OLED panels was decreased to 3.4ms by using an integrated gate driver circuit. The motion blur of large‐size OLED display panels was significantly reduced due to a decrease in the MPRT value.
